20100124203 | CONDITIONAL ACCESS TERMINAL INITIATION OF DELAYED HANDOVER - The number of handover-related failures that occur in a communication system may be reduced by taking target access point conditions into account when declaring radio link failure and/or by delaying certain handover operations. In some aspects, criteria for radio link failure detection and access terminal-controlled mobility may take into account access point parameters related to neighboring cells that may be available as mobility targets. For example, filtering mechanisms for detecting radio link failure based on radio layer problem reports may also take into account the availability of various neighbor access points and their measured signal strengths. In addition, a handover command may be sent earlier than in conventional systems (e.g., the handover command may be sent even though the target access point is weaker than the source access point) and include an indication that instructs the access terminal to delay handover until a specified condition is met. For example, handover may be delayed until the target access point becomes stronger than the source access point. | 2010-05-20 |

20100124205 | Distributed adaptive scheduling of communications among nodes in a mobile ad hoc network - Communications in a mobile network are scheduled by defining reservation frames having time slots during which network nodes can transmit certain traffic loads while avoiding interference. The nodes maintain maps that identify the slots as either free or reserved based on each node's existing reservations, and reservation information the node receives from neighboring nodes. A node wishing to transmit traffic determines the number of slots required to carry the traffic, selects a first set of slots from among those identified in its maps as free, and transmits a reservation initiation message (RIM) that identifies the first set of slots. Nodes receiving the RIM determine which, if any, of the first set of slots are already reserved based on their own maps, and transmit counter reservation initiation messages (CRIMs) if any slots are reserved. The CRIMs also identify those slots that the CRIM transmitting nodes determine to be currently free. | 2010-05-20 |

In an exemplary method for transmitting a broadcast/multicast signal, a pilot symbol sequence is obtained for each slot of one or more frames of the broadcast/multicast signal, so that the pilot symbol sequence varies for each slot of a given frame. The pilot symbol sequence for each slot is spread with a channelization code, and the spread pilot symbol sequence for each slot is scrambled, using a scrambling code, to form a first pilot channel signal. The first pilot channel signal is transmitted so that it is time-division multiplexed with one or more traffic channel signals transmitted during each slot and code-division multiplexed with a second pilot channel signal transmitted during all slots of the one or more frames. | 2010-05-20 |

The medium access protocol selected for a given message or traffic is determined according to one or more of (a) the size of the traffic, (b) the priority of the traffic, (c) the periodicity of the traffic, and (d) whether the traffic is broadcast or unicast to the other nodes in the network. Each radio includes one or more processor and memory modules configured to output messages or traffic for transmission from the radio according to the selected medium access protocol. By using distributed scheduling and traffic control to protect against hidden nodes, the radios can maintain agile portability in tactical urban environments. | 2010-05-20 |

20100124287 | TRANSMISSIONS WITH REDUCED CODE RATE IN 8VSB DIGITAL TELEVISION - Procedures performed prior to convolutional interleaving of 8VSB digital television signals restrict the alphabet of symbols in novel methods of generating trellis-coded digital television signals that include more robust symbol coding using a restricted alphabet of symbols selected from a full 8VSB symbol alphabet consisting of −7, −5, −3, −1, +1, +3, +5 and +7 normalized modulation levels superposed on a background modulation level. Certain of these novel procedures generate pseudo-2VSB or P-2VSB robust symbol coding with a restricted alphabet of symbols consisting of −7, −5, +5 and +7 normalized modulation levels superposed on a background modulation level. Others of these novel procedures generate prescribed-coset-pattern-modulation or PCPM robust symbol coding intermixing two restricted alphabets of symbols according to a prescribed pattern. One of the two restricted alphabets of symbols used in PCPM consists of −3, −1, +5 and +7 normalized modulation levels superposed on a background modulation level. The other of the two restricted alphabets of symbols used in PCPM consists of −7, −5, +1 and +3 normalized modulation levels superposed on a background modulation level. | 2010-05-20 |
20100124288 | DETECTION OF OUTBOUND MESSAGE SIGNALS IN A POWER LINE TWO-WAY COMMUNICATIONS SYSTEM - Improvements in the detection of TWACS outbound message signals. A first improvement involves matching some (or all) of the intermediate points in an outbound preamble occurring between bits of the preamble currently being detected. This reduces the possibility of a false synchronization and therefore decreases the probability of missing outbound message signals. A second improvement is to require some or all of the known preamble bits to exceed a predetermined threshold where both the thresh-old and which bits are adjustable. An additional approach is using 4-8 additional buffers in a transponder to detect preamble patterns in the outbound message. Each half cycle of the outbound message waveform requires entering a bit only into the buffers active for the particular frame of reference in which the message is being transmitted, since only buffers for that frame of reference are employed. The process continues until all bits specified to be sent, based on the length of the outbound message, are extracted. A CRC is then performed for the message. Using this method eliminates the problem of inbound messages being detected as outbound messages, and the resulting “blindness” of the transponder. It further makes the transponders less sensitive to noise which currently causes the transponder to detect a preamble when there is none, resulting in a valid outbound message being missed. | 2010-05-20 |
20100124289 | TRANSMISSION SUPPRESSION - A transmission suppression apparatus includes a first modulator that converts a symbol to a waveform. The apparatus further includes a first non-linear filter, configured to at least partially compensate for non-linear distortions of a transmission signal path. The apparatus further includes a first medium coupling device for coupling signals to a communication medium. The apparatus further includes a second medium coupling device for coupling signals from the communication medium. The apparatus further includes summing circuitry with a first input connected to an output of the second medium coupling device. The apparatus further includes cancellation circuitry, connected to a second input of the summing circuit, that converts the symbol to an analog waveform that is substantially 180 degrees out of phase with the analog waveform encoding the symbol on the first input to the summing circuit. | 2010-05-20 |
20100124290 | Digital Signal Transmission for Wireless Communication - A signal is digitally processed for transmission based on a digital baseband input signal. The digital signal is modulated to generate a digital pulse signal at a sample frequency, and an RF transmit signal is generated at a transmit frequency responsive to the pulse signal, where the sample frequency is a multiple of the transmit frequency. In various embodiments, a digital transmitter implementing the invention includes a baseband modem, a modulator, and an amplifier. The modem operates on a digital input signal at a baseband frequency and generates a processed signal which is modulated by the modulator, such as a sigma-delta modulator, to generate a digital pulse signal at a sample frequency. The digital pulse signal drives the amplifier which produces a RF transmit signal at a transmit frequency for transmission using an antenna. | 2010-05-20 |
20100124291 | Receivers for Embedded ACK/NAK in CQI Reference Signals in Wireless Networks - Within a wireless network, uplink control information (UCI) transmitted by user equipment is received by a base station. The UCI includes a least two elements, a first set of symbols produced using a first information element and a second set of symbols produced using a second information element. At least a first metric is produced using the first set and the second set of received symbols. The first information element may then be detected using the first metric. | 2010-05-20 |
